Ever wonder what all those processes running on your Windows system are for?

Press Ctrl-Alt-Delete to load Windows Task Manager, then click the "Processes" tab to see them.  Some are easy to figure out.  "IEXPLORE.EXE" is Internet Explorer.  "winamp.exe" is Winamp.  Most commonly known processes have an associating application listed under the "Applications" tab.

But, what about the others?

Use LIUtilities

LIUtilities' website is your solution.  It explains most, if not all, of the processes you will ever want to inquire about.  Use Google's site specific search function to search only LIUtilities' site:

Google search... http://www.google.com/search?q=site%3Aliutilities.com+winlogon.exe

#1 Google result... http://www.liutilities.com/products/wintaskspro/processlibrary/winlogon/

Instantly, you have the information you seek:

What If LIUtilities Does Not Have My Process?

If LIUtilities does not have the process you are looking for, then simply do a regular Google search on just the process name.  The reason I suggest searching LIUtilities first is because their results are very trustworthy, and other results may or may not be as trustworthly.  If you are ever unsure about a certain website's results, please continue your search and check out multiple websites about the same process until you are comfortable that you have found the proper solution.  If the process you are searching for is a legitimate well-known process, then you will be able to find an explanation for it in Google.

You might also be aware that any virus or spyware can be renamed by their companies to have any process name they want.  Maybe of them rename their horrid processes to the same name as typical processes found on your computer, so that you will not detect and delete them.  You should always be aware of this possibility.

To detect virus and spyware processes that are renamed to the same process name as a regular Windows process, you may have to start paying attention as to when the process starts and stops and compare it with when the Windows process should start and stop.  Other considerations are memory usage and file sizes, if you can find the process file on your hard drive.
